Posing alongside her younger sister Eugenie at the Victoria and Albert Museum Summer Party in London, the 28-year-old cousin of Prince William and Harry quickly realized the fashion faux pas and adjusted her navy skirt before stepping inside.

Girl, we've all been there before. And the fashion blunder doesn't take away from the gorgeous Self-Portrait dress, which is currently on sale!

Seeing as Beatrice recently ended her 10-year relationship with Uber executive Dave Clark, it's no surprise she is turning up the sex appeal when it comes to her wardrobe.

The British royal infamously made headlines for her fashion choices in 2011, when she attended the wedding of William and Kate Middleton wearing what many deemed a "pretzel hat."

At the time, designer Philip Treacy defended the fascinator, saying, "What more can I say? You know, I loved that hat, I thought she looked like a porcelain doll," he said. "That was the idea. I have known her for a long time. Isabella [Blow] introduced me to her when she was young. Isabella’s motto was always ‘Get them when they are young!’, so she wanted Beatrice to get into hats. She is a sweet girl and it’s not an easy life.”

While Beatrice definitely did not land on the best-dressed lists, her topper did raise over $130,000 for charity at auction.
